Title: Upgrading aluminium ores - by wet grinding, screening, magnetic sepg., desliming etc.
Inventor: WESTON DAVID
IPC: C01F7/02
Filed: 1980-09-08
Abstract: Aluminium mineral bearing material is upgraded by (a) wet grinding at a pulp density of 25-60% solids in the presence of NaOH and opt. KOH, NH4OH and/or Na2CO3, the pH being 8.5-12.5 (pref. 9.5-12.5); (b) screening the pulp, at least once, to produce a 10-65 mesh Tyler product, the screen size used being at least 10% less than the width of the magnetic gap in (c); (c) subjecting the prod. from (b) to at least one high intensity magnetic separation using a field strength of 11-22 kG; and (d) desliming the non-magnetic product. Step (c) produces a magnetic concentrate enriched in Fe and Ti minerals and a non-magnetic prod. impoverished in Fe and Ti minerals. Step (d) produces a fine product enriched in Fe, Ti and silica and a coarse prod. impoverished in Fe, Ti and silica. The process is esp. for upgrading bauxites and bauxitic clays. The process is low-cost and gives only low losses of Al-bearing minerals. In (a) a dispersant can be added to the pulp, selected from lignins, silicates and/or phosphates. In (b) screening is pref. to 10-35 mesh (if an optional low magnetic intensity (0.5-10 kG) sepn. stage is included), or to 20-65 mesh (if high magnetic intensity sepn. only).

Title: Device for drawing off sterile liquids, such as milk or the like, in a metered fashion
Inventor: REINECKE GUENTER
IPC: B65B39/00
Filed: 1981-04-23
Abstract: In the case of a device for drawing off sterile liquids in a metered fashion, throughflow may be blocked, for example in the case of liquids containing solid bodies, such as fruit yoghurt, by the sticking of solid pieces to the sealing plug arranged in the cross section of flow. The object of the invention is therefore to make it possible to increase the output of a metering device by keeping the cross-section of flow free of such structures. The solution is brought about, as Figure 1 shows, by arranging a roller membrane (4) in front of the inlet aperture (20) leading into the filling pipe (3) and a convex membrane (5) with a spherical surface behind the outlet aperture (21) leading out of the filling pipe (3), the two membranes moving perpendicularly to the direction of flow. This ensures that the cross-section of flow remains free of structures during metering.   <IMAGE>

Patent DE-3142152-A1 (DE)
Inventor: KOSZYTORZ GUENTHER
IPC: B23K26/08
Filed: 1981-10-23
Abstract: An apparatus for automatically adjusting the characteristic of a deflection unit, illustratively of the type used in laser recording equipment. A reference value for the deflection unit is conducted to a first input of a multiplier, the second input of which is connected to the output of a first memory. The output of the multiplier is connected to a first input of an adder, the second input of which is connected to the output of a second memory. In addition, a comparator is provided which compares the position of the deflection unit with two adjustment reference values. The content of the second memory is varied in response to a zero-adjustment command until, for a predetermined reference value zero, the deflection unit has assumed a zero position. Upon the issuance of a slope-adjustment command, the content of the first memory is varied until, for a second adjustment reference value, the deflection unit has assumed its desired position. The contents of the memories are preserved so that a reference value which is predetermined in normal operation is corrected so that the characteristic of the deflection unit agrees with a desired characteristic.

Title: Method and device for operating a monovalently alternative absorption heating installation
Inventor: GRUBER FRANZ
IPC: F24D3/18
Filed: 1981-12-10
Abstract: The invention relates to a method for operating a monovalently alternative absorption heating installation, which works in heat pump operation above a predetermined ambient temperature and in direct heating operation in the event of lower temperatures. In order to be able to handle such an absorption heating installation easily in terms of regulation technology and to achieve a good heating figure even during direct heating operation, it is proposed according to the invention that, for switching over to and also during direct heating operation, refrigerating medium is drawn off from the part of the absorption heating installation which is under great pressure during heat pump operation. In this connection, refrigerating medium must be drawn off in a quantity which is sufficient to reduce the pressure in this part of the absorption heating installation to a value below the pressure at which the refrigerating medium just still condenses in heat exchange with heating medium. Drawn-off refrigerating medium is pressure-relieved and absorbed in vapour state by solvent which is low in refrigerating medium.

Title: A process for producing mouldings from fine-grained raw materials for use in a shaft furnace
Inventor: STAEDING WILHELM
IPC: C21B5/00
Filed: 1981-12-10
Abstract: The invention provides for the use of fine-grained starting materials in a blast furnace, such as are frequently available as iron carriers. These can be magnetite, mill scale and also oxidic dusts from gas purification. Usually, the said materials are pelletised or sintered, but the attrition resistance is then not fully satisfactory. To avoid this, the said starting materials are mixed with 5 to 16 % by weight of a pulverulent lime alumina cement and with the required quantity of water and bonded to form lumps, so that a concrete-like product is formed which, with respect to its strength, is well matched to the blast furnace campaign.
